Patent JP-S5535327-A (JP)
Title: Beam splitter
Inventor: HORIMATSU TETSUO
IPC: G02B5/30
Filed: 1978-09-04
Abstract: PURPOSE: To provide the beam splitter which has perfectly eliminated back reflection by using the electro-optical crystal whose angle assuming to the optical axis is Brewster's angle.  
     CONSTITUTION: The angle 27 that incident light 19 assumes to an electro-optical crystal 26 is so set that the angle 24 becomes Brewster's angle. When the polarizing direction of the incident light 19 is assumed to be perpendicular to the incident face, part of the incident light 19 is reflected by the face 22 and part advances in the crystal 26 but its polarization direction changes owing to electro-optic effect. If the thickness 25 of the crystal 26 is suitable selected, the polarization direction may be rotated exactly 90° at the back 23. Then, the polarization direction is within the incident face at the face 23 and since the angle 24 is Brewster's angle, it turns out that the light transmits without causing back surface reflection. If the polarization direction of the incident angle 19 is within the incident face, making the angle 27 Brewster's angle obviates reflection on the face 22, resulting in that the light reflects partly on the back surface 23 and partly transmits.

Title: Power generator
Inventor: KAWAI TERUO
IPC: H02K7/00
Filed: 1993-04-09
Abstract: PURPOSE:To generate a strong rotary force by a method wherein both the magnetic force of a permanent magnet which is exhibited through a circular magnetic unit and the magnetic force of an electromagnet are utilized. CONSTITUTION:An electromagnet 1a which is brought into contact with a circular magnetic unit 2 is within the magnetic field of a permanent magnet 3. If a current is applied to an electromagnet 1b adjacent to the electromagnet 1a, the flux 3a of the permanent magnet 3 is instantaneously converged by the electromagnet 1b to form a magnetic domain. As a result, the magnetic unit 2 is strongly attracted by the electromagnet 1b and the contact point of the magnetic unit 2 is shifted to the electromagnet 1b side. Being shifted further, when the contact point of the electromagnet 2 comes close to the center of the electromagnet 1b, a current is applied to an electromagnet 1c and, at the same time, the current application to the electromagnet 1b is discontinued. By repeating these processes, the magnetic unit 2 is turned. Thus, the rotation of the magnetic unit 2 is transmitted to a nonferrous power shaft through a universal joint as a rotary movement.

Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To avoid incomplete combustion and reduce the discharge of NOx from a gas turbine engine by a method wherein a turbo generator is provided with a permanent magnet generator, a combustor and a recuperator. SOLUTION: Intake air is induced by a compressor 30 through a permanent magnet generator 20 while the compressor 30 increases the pressure of air and sends the air into a recuperator 23. The waste heat of the turbine 31 is used to preheat air before advancing the air into a combustor 22 while preheated air is mixed into fuel to burn the same. Combustion gas is expanded in the turbine 31 subsequently and drives the compressor 30 as well as the permanent magnet rotor 26 of the permanent magnet generator 20, mounted coaxially with the turbine 31. The expanded exhaust gas of turbine is passed through the recuperator 23 before discharging the same out of a turbo generator 12. According to this method, incomplete combustion can be avoided.

Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To secure contact bonding force required for the slit plate of a loading post in loading and at the same time achieve loading with less load. SOLUTION: In a guide pin projecting downward from the slit of a loading post that is provided so that it can travel between unload and load positions while being guided by the slit of a slit plate, the first and second links A and B of a sledding link where a tip part is connected and a base edge part is driven by a gear are bent in a shape near a connection part as in (a) and (b) [a]. A figure shows a state where the tip part of the link A has not been connected to the guide pin of the loading post. When the tip part is connected to the guide pin, deflection results, the deflection in loading becomes large, and that in unloading becomes small [a].

Title: Device for suspending/clamping tissue paper box
Inventor: YAMADA TOMIO
IPC: A47K10/18
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To use safely instantaneously tissue paper when needed especially when used in an automobile by mounting a magnet so as to clamp a box at one side of a clamping body obtained by working a plate-shaped member into a U-shape. SOLUTION: A magnet is mounted to a clamping body in which a magnetic body is located at the back side 6 of a tissue paper box 3 and is used in a suspended state at a steel part of a ceiling, a window frame, or a door by its magnetic force. By sticking a chip made of steel to any given location with a double-sided adhesive tape in the case that there is no steel part at a desired part for installation, it is possible to mount and use the suspending/clamping device. Therefore, there is no need for placing it on an arm rest, between a passenger seat and a driver's seat, or the like without interference in an automobile to enable the use of its inside. As the tissue paper box 3 is installed to a ceiling, a window frame, or the like, it is easy to take tissue out. In addition, as the box 3 is placed upside down, it is possible to take tissue to the last easily.
